Unless youre running a massive mining operation in a location with low electricity costs (like China), then in my opinion it does not make sense to mine Bitcoin anymore.
Youre far better off investing your efforts in just buying alt coins and credible ICOs.
I think he can try with other coins because the opportunity is wide open and if they can get low electricity costs like you said, then I am sure that if they have a big mining hardware in their home, they can make a lot of money. and from this, I think if they can save more bitcoin and only cash out when they really need money, then I think they can make a living on bitcoin.
